The GPS receiver chosen for this challenging measurement has been the Leica Viva GS14, desi-gned for the most demanding environment. This GNSS receiver exceeds the toughest environ-mental specifications, going beyond industrial standards ensuring flawless performance even in the most challenging work places.
The instrument chosen for this delicate performance was the latest offspring of the Leica-Ge-osystems family, the famous company which produces high accuracy topographic instruments. This instrument, the Leica VIVA GS14, was lent to the expedition by Leica for the testing of its performances as regards portability, resistance to very low temperatures and to rugged use on rough tracks.
The instrument, presented to the researchers the day before their departure from Italy, is com-posed by an antenna which also contains the electronics and the data memorizing system, and by a controller linked via Wi-Fi to the antenna. The controller works like a computer that provi-des the right parameters to be used for the measurement.
The scientific expedition was carried out between June 22nd and the beginning of August 2014 and involved two Pakistani researchers Aamir Asghar and Hameed Fahad and two Italian rese-archers, Marcello Alborghetti and Giorgio Poretti, as well as the participation of Maurizio Gallo.
The expedition and the research were carried out with the patronage of the Italian Presidency of the Council of Ministers, the Ministry of Foreign Affairs and the Ministry of the Environment
